STEP 3: Using basepad as a guide, mark spots on concrete where 4 holes will be
drilled (see Figure 3).
STEP 4: Drill four pilot holes in pad, ensuring that the hole is at least 1/4” deeper
than the concrete screw being used.
STEP 5: Center basepan over pre-drilled holes and insert concrete screws.
STEP 6: Tighten concrete screws.
NOTE:
Do not over-tighten the concrete screws. Doing so can weaken the
integrity of the concrete screw and cause it to break.
STEP 7: Finish unit assembly per unit’s installation instructions.
